Description

Cleaning nozzle device

The invention relates to a cleaning nozzle device, comprising a holder for fixing the cleaning nozzle device, a fluid nozzle device, which is arranged on the holder and by means of which a surface to be cleaned can be acted upon with fluid, a first active device, which is arranged on the holder and by which can be acted upon by mechanical contact on the surface to be cleaned, and a second active device, which is arranged on the holder and through which on the surface to be cleaned by mechanical contact can be acted, the second active device relative to the first active device movable is, with a definable first position of the second active device relative to the first active device, which is a working position for the first active device and with a definable second position of the second active device relative to the first active device, which is a working position for the second Wi is strength device.

A cleaning nozzle device of the aforementioned type is used, for example, in connection with a steam suction device. The Dampfsauggerät provides steam as fluid, which is applied via the fluid nozzle device of the cleaning nozzle device to the surface to be cleaned. About the holder can be the cleaning nozzle device, for example, on a hose releasably or permanently fixed.

Depending on whether the second active device is in the first position or in the second position, an operator can decide how he wants to act on the surface to be cleaned. For example, the first active device is a peeling device, via which liquid can be drawn off from the surface to be cleaned, in particular in order to suck in dirt-laden liquid. The second active device is, for example, a wiper device in order to clean the surface, in particular by friction. The invention has for its object to provide a cleaning nozzle device of the type mentioned above, which allows a user with extensive cleaning options easy handling with a compact design.

This object is achieved according to the invention in the above-mentioned cleaning nozzle device in that at least one definable third position of the second active device is provided relative to the first active device, which lies between the first position and the second position and which for both the first and the first device for the second active device is a working position and / or in which is adjustable by adjusting an angular position of the holder relative to the cleaning surface, whether the first active device or the second active device contacted the surface to be cleaned.

In the solution according to the invention, at least one third position exists in addition to the first position and the second position. In this, both the first active device and the second active device can contact the surface to be cleaned. This makes it possible, for example, at the same time to carry out a removal operation and wiping or friction cleaning process. There are increased cleaning possibilities. It is alternatively or additionally possible for a user in a simple manner if the second active device is in the third position to achieve, by a small variation in the angular position, that either only the first active device or only the second active device corrected cleansing surface. The angle range in which the cleaning nozzle device is positioned to the cleaning surface, while staying within a working range, so that there is a simple ergonomic handling for the user.

The cleaning nozzle device according to the invention can be constructed compact. Through them, different cleaning processes can be realized with the same cleaning nozzle device; a user needs to do this do not change the nozzle device with respect to the corresponding device. The transition between different positions can be done easily. In particular, a corresponding adjustment of the desired working process (for example, only wiping, only sucking or wiping and sucking together) is possible by means of a mechanical switchover on the cleaning nozzle device.

In one embodiment, one active device of the first active device and the second active device is a scraper device, and the other active device of these two active devices is a rubbing or wiping cleaning device and in particular a brush device and / or cloth device and / or sponge device. As a result, it is easily adjustable for a user, for example, if he performs only a removal operation (in particular including suction), only a Reibreinigungsvorgang or Wischreinigungsvorgang, or both options together provides.

In a constructive and favorable handling embodiment, the second active device is arranged displaceably and in particular linearly displaceably on the holder. This makes it easy to achieve a transfer between different positions and the design effort can be kept low.

It is particularly advantageous if a fluid channel device is provided which is in fluid-effective connection with the fluid nozzle device. As a result, a surface to be cleaned can be exposed to fluid such as steam and / or a cleaning fluid.

It is also advantageous if a suction channel device is provided which is in fluid-effective connection with at least one suction opening. It can thereby aspirate liquid from the surface to be cleaned. The fluid channel device and the suction channel device are in particular arranged or formed on the holder. It is advantageous if the at least one suction opening is arranged in the region of an active device, which is a scraper device. As a result, can be sucked on a surface to be cleaned stripped liquid.

It is also advantageous if the at least one suction opening is arranged between the wiper device and the fluid nozzle device. As a result, when the cleaning nozzle device in a direction which is a follower direction between the scraper device and the Fluiddüsen- device, in a certain area initially act on fluid and in the movement process then liquid is stripped and can be vacuumed. The liquid comprises, for example, condensed vapor or a liquid which has been applied via the fluid nozzle device.

In an advantageous embodiment, the holder has a first region with a first center plane and a second region with a second center plane, wherein the first active device and the second active device sit on the second region and the second center plane lies at an angle to the first center plane. As a result, the cleaning nozzle device is formed angled. A user can then, for example, keep them at the first area with a corresponding distance to the surface to be cleaned, with an ergonomic handling is possible.

It has proved to be ergonomically favorable if the angle between the second center plane and the first center plane lies in the range between 10 ° and 40 ° and in particular between 20 ° and 30 °. It is advantageous if, in the third position of the second active device, when the first active device and the second active device contact the surface to be cleaned, a center plane of a region of the holder on which the first active device and the second active device are arranged an angle between 15 ° and 35 ° (in particular at an angle between 20 ° and 30 °) is oriented to a normal of the surface to be cleaned. This results in an optimized handling for a user. In particular, the center plane of the region of the holder on which the first active device and the second active device are arranged (the second center plane) at an angle between 15 ° and 35 ° (in particular between 20 ° and 25 °) is in an operating point working position of the respectively acting action position °) to the normal of the surface to be cleaned. In such an operating point working position (or in the corresponding angular range) results in an ergonomically optimized working with optimized cleaning effect.

The aforementioned object is further achieved according to the invention in that the second active device is seated on a guide device which has spaced guide rails. As a result, a defined transition between the first position and the second position and possibly the first position and the third position or the second position and the third position can be performed in a simple manner.

In particular, a first guide strip and a second guide strip are respectively arranged at or in the vicinity of opposite outer sides of the holder. These outsides lie in particular on a cuboid region of the holder. Thereby, a clearance is provided between the guide rails, which can accommodate a mechanism for shifting operation and / or detection of excellent positions of the second operating device. Optionally, this mechanism can also be arranged in a housing and thereby protect against damage and contamination.

In particular, the guide rails sit on a housing of the holder. Such a housing has, for example, a flow space for sucking of dirt-laden liquid and / or a flow space for applying fluid.

For the reasons mentioned, it is advantageous if a mechanism for actuating the movement of the second active device and / or position detection of the second active device is arranged between the guide rails.

It is favorable if an operating element which can be operated by a user is provided for a movement of the second active device. This results in a simplified handling for a user. By accessing the actuating element, a changeover between the various positions can be achieved in a simple manner. The actuating element may for example be or comprise a rotary element

Be shift element or comprise, be a switch element or include etc. In particular, a conversion of a movement of the actuating element (such as turning, pushing or switching) takes place in a movement of the second active device. In a structurally simple embodiment, the actuating element is a rotary element or comprises such. By rotation on the rotary element, a transition between different positions can be achieved. It is particularly advantageous if the confirmation element is arranged so that a user can access it from an upper side of the cleaning nozzle device or from a left outer side or right outer side, wherein an underside of the cleaning nozzle device opposite the upper side faces in the cleaning process of the surface to be cleaned. Thereby, a user can easily perform a changeover to the cleaning nozzle device to obtain the corresponding excellent position for the second active device. He has to interrupt his cleaning process only minimally. In particular, a guide device for guiding the movement of the second active device is designed so that upon reaching the first position and / or second position and / or third position, an automatic fixed position takes place. As a result, the design effort for the cleaning nozzle device is minimized. Furthermore, easy handling for a user results.

It is favorable if a force required to move the second active device between the first position and the third position and / or between the third position and second position is smaller than a force required to form out of the first position and / or second position and / or third position. As a result, a kind of self-locking effect is achieved when an excellent first position or second position or third position is reached.

In one exemplary embodiment, a slide track device, on which the second active device is guided, is provided for transmitting the motion to the second active device. As a result, a rotary movement can be converted into a linear movement in a simple manner, for example via a rotary element. In an alternative embodiment, a movement transmission to the second active device can be achieved in a simple manner via the slide track device, for example via a sliding element. It can thus be achieved with appropriate training of the slide track in a simple way a finding of excellent positions.

In one embodiment, it is provided that the slide track device comprises a slide track and a link element, which is guided on the sliding track. It can thereby be transmitted, for example, a force on the link element, or on the link element on the

Transfer gate path to effect a movement and in particular to effect linear movement. The link element is for example a Pin element, which is formed in a recess, or a roller element which is guided on the corresponding slide track.

In one embodiment, the link element is firmly connected to the second active device. As a result, a force can be transmitted to the link element via the slide track device and the link track, which in turn allows the second active device to be displaced.

In one embodiment, the slide track on a main direction, which lies at an acute angle to a direction of movement of the second active device. As a result, for example, a rotational movement of an actuating element can be converted into a displacement movement in one direction in a simple manner. It is favorable if the first position and / or second position and / or third position are defined by regions in the slide track, which are aligned at least approximately perpendicular to the direction of movement of the second active device. In these areas, the orientation of the slide track is different from the main direction. This makes it easy to achieve automatic detection.

It is advantageous if a lever element is provided, which on the

Sliding element acts and itself has a guide element, which is guided on a guide track, which is oriented parallel to the direction of movement of the second active device. The lever element is integrally or multiply connected to an actuating element such as rotary member. It can then easily implement a rotary motion in a linear motion. The guide element is for example a pin element, which is immersed in a recess which forms the guideway. In an alternative embodiment, the guide element is a roller element which is guided on the guide track. It is advantageous if the guideway and the slide track are formed in the same driver element. The driver then provides for the implementation of a particular rotational movement in a linear displacement of the second active device. The driver element is, for example, a grid plate, which is made of a plastic material or metal material. Such a driver element can be formed flat. As a result, the corresponding mechanism for the displacement operation (and possibly also determination of excellent positions of the second active device) can be formed in a simple and space-saving manner.

In an alternative embodiment, a gear transmission is provided, via which the slide track device or the second active device is movable. In this case, the toothed gearing can move the sliding track device, on which the second active device sits, in particular, immovably, or the toothed gearing can act directly on the second active device. The toothed gearing may in particular be designed to be self-locking, so that the first position, the second position and the third position (and optionally also other positions in addition to the third position between the first position and the second position) are predetermined, which are detectable, that is, which allow a work without being solved by usual working movements with the cleaning nozzle device a detected position.

In one embodiment, the gear transmission includes a gear and a rack on which the gear acts. As a result, a linear movement can be realized, for example, via a rotational movement of the gearwheel.

In one embodiment, the gear is rotatably connected to an actuating element and the rack firmly connected to the slide track device or the second active device. This can be realized by a rotational movement of the gear a linear movement. If the rack is firmly connected to a slide track device, then leaves form the gear transmission in a simple manner. For example, can be realized on the rotational movement of the gear, a linear movement of the rack and on the slide track device, in turn, this linear motion can be converted into a linear transverse movement of the second active device.

An embodiment of an inventive

Cleaning nozzle device, which is shown in Figures 1 to 9 and designated therein by 10, is intended for use with a steam cleaning device and in particular steam-suction cleaning device. The cleaning nozzle device 10 is formed in one embodiment as a unit, which is in particular releasably fixed via a holder 12 on the device. The cleaning nozzle device 10 is provided, for example, for releasably fixing to a handle unit, wherein the handle unit, for example, sits non-releasably on a hose. It may in principle also be provided that the corresponding cleaning nozzle device is permanently connected to the device or a hose or a handle unit.

In the embodiment shown, the holder 12 comprises a first region 14, to which a second region 16 adjoins. The first

Region 14 of holder 12 has a first center plane 18 (see, for example, FIG. The second region 16 has a second center plane 20. The first center plane 16 and the second center plane 18 are at an acute angle 22 to each other, which in particular in the range between 10 ° and 40 °, preferably in the range between 15 ° and 35 ° and preferably in the range between 20 ° and 30 °. In the embodiment shown, this acute angle 22 is approximately 22 °. This angular formation facilitates a user's cleaning process. The first region 14 of the holder 12 is for example at least approximately cylindrical and has an inner recess 24, via which the cleaning nozzle device 10 can be fixed to a flexible hose of a device.

The second region 16 has a lower part 26 and a top 28. The upper part 28 is placed on the lower part 26 and these form a housing 30 with a housing interior.

The lower part 26 and the upper part 28 each have a rectangular cross-section area 34a, 34b, which is oriented transversely to the first region 14 and has a greater width than this. The cuboid regions 34a, 34b extend to the left and to the right away from the first region 14.

The lower part 26 is in particular integrally connected to the first region 14. From the recess 24 of the first region 14 opposite walls 36a, 36b lead to a respective lateral outer side 38a, 38b of the lower part 26. A corresponding wall 36a, 36b in this case has a sloping region 40a, 40b, wherein the distance between the inclined regions 40a, 40b extended to an end 37. The oblique area 40a, 40b is adjoined by mutually parallel areas 42a, 42b of the walls 36a, 36b. As a result, a flow space 44 is defined in the housing interior 32. This flow space 44 is in fluid-effective connection with the recess 24. At the end 37 suction openings 46 are formed or arranged. These are in fluid-effective connection with the flow space 44 and the recess 24. As a result, a suction channel device 48 is formed, so that suction material can be sucked in via the front end 37 of the second region 16.

The walls 36a, 36b are in particular integrally formed on the lower part 26 and integrally connected to the first region 14. The upper part 28 forms a housing cover for the lower part 26. Accordingly, the upper part 28 is adapted in its shape to the lower part 26. The upper part 28 in this case has a partial neck 50, which is in particular integrally connected to the upper part 28. This partial piece 50 is placed on the areas 42a, 42b of the walls 36a, 36b to form a closed suction channel device 48 between the recess 24 and the suction openings 46.

On the lower part 26 a between the outer sides 38a, 38b at the front end 37 extending recess 52 is formed. This recess 52 can receive a partial region 54 of a puller lip 56, which is in particular a rubber lip, and thereby hold it on the lower part 26 and, in turn, on the holder 12.

In one embodiment, this puller lip 56, which is a first puller lip, has a step 60 between the portion 54 and a front end 58. An area between the step 60 and the front end 58 may thereby abut against the front end 37 on a wall forming the outside 38a, 38b.

In the vicinity of the front end 37 are arranged parallel spaced webs 62. A respective suction opening 46 is formed between adjacent webs 62. The webs 62 have an upper side 64, which is designed for inserting a second Abzieherlippe 66. The second puller lip 66, which is in particular a rubber lip, has a thickening region 68, which is intended for insertion. The upper part 28 is formed such that when it is seated on the lower part 26, the first puller lip 56 and the second puller lip 66 are held non-slip with respect to the housing 30 in their corresponding position. These are on the upper part 28 corresponding investment elements for the first puller lip 56 and the second puller lip 66. The first puller lip 56 and the second puller lip 66 are parallel to each other. The first puller lip 56 and the second puller lip 66 form an active device 70 (first active device), which is a puller device and by means of which a surface 72 to be cleaned (FIG. 7) can be acted upon by mechanical contact. By means of the stripping device 70, liquid can be drawn off the surface 72 to be cleaned. About the Saugkanal- device 48 with the suction ports 46 can be the corresponding

Aspirate liquid (which is then particularly dirty).

At the first region 14, a fluid channel device 74 is arranged. On the holder 12, a fluid nozzle device 76 is arranged on the lower part 26, which comprises a plurality of fluid nozzles 78, wherein these fluid nozzles 78 are arranged below the suction openings 46. The fluid channel device 74 is fluidly connected to the fluid nozzle device 76. Fluid (in particular water vapor and / or a cleaning fluid) can thereby be supplied through the fluid channel device 74 to the fluid nozzles 78, which are located at the front end 37 of the housing 30, and the surface 72 to be cleaned can be supplied with fluid.

The suction openings 46 are located between the first active device 70 with the Abzieherlippen 56 and 66 and the fluid nozzle device 76. If a

During the cleaning process, the user moves the cleaning nozzle device 10 in a direction 80, which is a follower direction from the first device 70 to suction openings 46 to the fluid nozzle device 76, then a certain surface area of the surface 72 to be cleaned is laterally fluid first and then the first device moves 70 over the fluid-loaded area. Accordingly, it is then possible to suck off (dirt-laden) liquid (which contains condensed steam and / or discharged cleaning liquid) via the suction openings 46. On the holder 12, a second active device 82 is arranged on the lower part 26. The second active device 82 is a friction or wiper cleaning device, by means of which a cleaning effect or wiping effect can be achieved by mechanical contact with the surface 72 to be cleaned by way of a friction movement.

In the embodiment shown, the second active device 82 is a cloth cleaning device which comprises a cleaning cloth 84 which is arranged on a corresponding tool holder 86.

It is also possible, for example, that the friction / wiper cleaning device is a brush device which comprises brush rims for friction cleaning, or a sponge device which comprises one or more sponges for friction cleaning. The second active device can also combine, for example, two or more different active elements such as cloth, sponge, brush, etc.

The second active device 82 is held linearly displaceable on the holder 12 via the lower part 26.

The tool holder 86 is fixed to a bridge element 88 and inserted there, for example, in a corresponding recess 90. This recess 90 and a corresponding immersion region of the tool holder 86 are designed in such a way that positive locking is achieved in all directions transversely to the insertion direction.

The lower part 26 has a lower side 92, which faces away from the side on which the walls 36a, 36b sit. The lower part 28 has on the outer sides 38a, 38b on the underside 92 projecting walls 94a, 94b (see Figure 3), which limit the bottom 92 laterally. On the underside 92 of the lower part 26, a guide device, designated as a whole by 96, for a linear displacement guide of the second active device 92 is arranged. A displacement direction 98 of the second active device 82 relative to the holder 12 and thus relative to the first active device 70 is at least approximately parallel to the second center plane 20th

The first active device 70 and the second active device 82 have a front end, which lies at least approximately on a line 100 or 102 or an enveloping line of the corresponding front end is the line 100 or 102. The movement direction (displacement direction) 98 is transverse and in particular perpendicular to the lines 100, 102.

The guide device 96 comprises a first guide strip 104 and a second guide strip 106. These are spaced from one another on the lower part 26 on the underside 92 thereof. The first guide rail 104 is arranged on or in the vicinity of the (outer) wall 94a. The second guide rail 106 is located at or near the (outer) wall 94b. The distance between the first guide rail 104 and the second

Guide rail 106 is in particular much larger than the distance of the guide rail 104 to the wall 94 a and the distance of the

Guide bar 106 to the wall 94b. In particular, the distance between the first guide strip 104 and the second guide strip 106 is at least 70% of the total width of the second active device 82 in the spacing direction.

In one embodiment, the first guide member 104 and the second guide member 106 are each formed as round rods. To the

Bridge element 98 is a first guide plate 108 is disposed with a recess 110 in which the first guide rail 104 is immersed. Accordingly, on the bridge element 88, a second guide plate 112 is arranged with a recess 114, in which the second guide strip 106 is immersed.

Between the first guide rail 104 and the second guide rail 106 is a designated mechanism 116 for the shift operation of second active device 82 is arranged relative to the first active device 70 and for determining specific positions of the second active device 82 relative to the first active device 70. It is provided a driver element 118, which is designed as a grid plate and is positioned between the guide rails 104 and 106.

This cam element 118 comprises a slide track device 120 with a slide track 122. This slide track 122 (cf., for example, FIG. 3) has a main direction 124 which lies at an acute angle 126 to the slide direction 98. In one embodiment, this acute angle 126 is in the range between 60 ° and 70 ° and, for example, at about 65 °.

At the slide track 122, a first region 128 is defined, which has an orientation not in the main direction 124 but at least approximately perpendicular to the displacement direction 98. This first region 128 is defined at a first end 130 of the slide track 122. At an opposite second end 132 of the slide track (see FIG. 6), a corresponding second area 134 is defined with an orientation at least approximately perpendicular to the displacement direction 98.

Between the first end 130 and the second end 132, a third region 136 is defined with a corresponding orientation at least approximately perpendicular to the displacement direction 98. The first region 128, the second region 134 and the third region 136 provide certain excellent positions of the second active device 82, as will be explained in more detail below.

At the bridge element 88, a link element 138 is arranged, for example in the form of a pin member. This link element 138 sits, for example, centrally between the first guide rail 104 and the second

Guide strip 106. This link element 138 is immersed in the slide track 122. The slide track device 122 further comprises a guide track 140 on the driver element 118. This guide track 140 is designed, for example, as a continuous recess. The guideway 140 is aligned in a direction parallel to the displacement direction 98.

On the upper part 28, a pivot bearing 142 is arranged with a recess 144. The recess 144 is oriented transversely and in particular perpendicular to the displacement direction 98. For actuating a displacement movement of the second active device 82, an actuating element 146 is provided. In one exemplary embodiment, this actuating element 146 comprises a rotary knob 148 on which a pin 150 is seated. This pin 150 is penetrated through the recess 144.

A gripping surface 152 of the actuating element 146, via which a user can access the actuating element 146, is accessible to the cleaning nozzle device 10 from an upper side 154 (cf., for example, FIG. 1 and FIG. The upper side 154 faces an underside 156 of the cleaning nozzle device 10, which faces the surface 72 to be cleaned during a cleaning process.

In the lower part 26, a continuation 158 of the pivot bearing 142 is arranged with a corresponding recess.

The pivot bearing 142 is arranged in one embodiment in the region between the partial nozzle 50 and the cuboid region 34b. The continuation 158 of this pivot bearing is on the lower part 26 outside the

Flow space 44, for example, behind the walls 40b and 42b arranged. There is provided a lever 160 which is rotatably connected to the pin with a corresponding pin connecting member 162. This lever 160 has a guide member 164 which is immersed in the (straight) guide track 140. A rotary operation of the actuator 146 via the lever 160 to a corresponding movement of the driver 118. By the link element 138, which is fixedly (immovably) connected to the second active device 82, and which is immersed in the slide track 122, then this rotational movement in a displacement movement of second active device 82 implemented in the displacement direction 98. Depending on the direction of rotation, a feed movement to the front or a return stroke movement to the rear takes place.

At the pivot bearing 142 sits a stop 166, which prevents over-rotation of the actuating element 146.

The second active device 82 has a first position 168 with respect to the first active device 70 (FIG. 7), which is a working position for the first active device 70. In this first position 168 of the second active device 82, the latter is retracted so far with respect to the first active device 70 that only the first active device 70 contacts the surface 72 to be cleaned when the cleaning nozzle device 10 is held in an operating point working position. The operating point working position is by a certain angular position or a certain angular position range of the second

Area 16 with respect to the surface to be cleaned 72 predetermined. For example, the second center plane 18 for this working position of the first active device 70 at an angle 170 between 15 ° and 35 ° and in particular between 20 ° and 25 ° to a normal 172 of the surface to be cleaned 72. In this operating point working then contacted only the first device 70 does not contact the surface 72 to be cleaned and the second device 82 when the latter is in the first position 168.

The first position 168 of the second active device 82 is present when the pin element 138 lies in the first region 128. The first position 168 is determined by the formation of the first region 128. There is an increased force required to lead the link element 138 out of the first region 128; it is a kind of self-locking effect achieved when the link element 138 is located in the first region 128. The force required to guide the pin element 138 out of the first region 128 is greater than the force required to guide the pin element outside the regions 128, 134, 136 in the main direction 124. The second active device 82 has a second position 174 (FIG. 8), which is a working position for the second active device 82. If the second active device 82 is in the second position 174 and contacts the surface 72 to be cleaned within the above-mentioned operating point working position, then the first active device 70 does not touch the surface 72 to be cleaned.

The second position 174 is defined over the second region 134 and detected via the formation of the second region 134. It is in comparison to the other displacement movement, an increased force required to bring out the link element 138 from the second region 134 of the slide track 122. By a kind of Selbsthemmeffekt, which is achieved by the formation of the slide track 122, an (automatic) determination of the second position 174 is reached. According to the invention, (at least) a third position 176 is provided (FIG. 9), which lies between the first position 168 and the second position 174. In the third position 176, both the first active device 70 and the second active device 72 may simultaneously contact the surface 72 to be cleaned when the cleaning nozzle device 10 is held in the working point working position with respect to the surface 72 to be cleaned. It is also possible by an operator within the operating point operating range by varying the adjustment angle (for example, by varying the angle of the second center plane 20 to the normal 172), to set whether only the first active device 70 or only the second

Actuator 82 contacted the surface to be cleaned 72. The angle variation lies within the operating point range, so that comfortable operation is still possible for a user and, for example, a hand holding the cleaning nozzle device 10 at the first region 14 does not contact the surface 72 to be cleaned.

In the third position 176 of the second active device 82, for example, at the same time, for example, at the same time a friction cleaning can take place via the second active device 82 and it can be pulled off via the first active device 70. By slightly varying the angle, an operator can "change over" to just-peel-off or just-to-grate-clean.

The third position 176 is present when the link element 138 lies in the third region 136. By the corresponding formation of the third region 136, an (automatic) determination of the third position 176 is achieved by a type of self-locking effect. The lead out of the link element 138 from the third area 136 for releasing the third position 176 requires a greater expenditure of force than a movement outside of excellent positions 168, 174, 176.

In principle, it is possible for the first position 168 and the second position 174 to have more than one excellent position. For example, this is achieved by appropriate design of the slide track 122, for example by a corresponding fourth area with a vertical orientation to the displacement direction, etc. is specified.

In the described embodiments are the excellent

Positions the first position 168, the second position 174 and the third position 176. It is also possible in principle that one or more positions according to the third position 176 continuously between the first position 168 and the second position 174 are adjustable. The implementation of a movement of the actuating element 146 to a displacement movement (and detection) of the second active device 82 can also be done in other ways than via a slide track device 120. For example, a corresponding gear transmission or rack gear can be provided or a coupling gear can be provided.

In one embodiment, it is provided, as indicated in Figure 3, that on the walls 94a, 94b, a lid member 178 sits, which covers the mechanism 116 and thus protects against dirt and damage.

The cleaning nozzle device according to the invention functions as follows (FIGS. 7 to 9). About the corresponding device of the cleaning nozzle device 10 fluid such as steam is supplied.

Via the fluid nozzles 78 of the fluid nozzle device 76, the surface to be cleaned 72 can be supplied with fluid. At the suction openings 46 is negative pressure and dirty liquid can be sucked off.

In the first position 168 of the second active device 82 (FIG. 7), this is in a non-working position. A fluid loading can be achieved and the corresponding surface can be drawn off via the first active device 70, if this is designed as a stripping device, and dirty water can be sucked in.

An operator can, via actuation and in particular rotation of the actuating element 146, bring the second active device 82 into the second position 174 (FIG. 8). In this second position 174, which is a working position for the second active device 82, a region of the surface to be cleaned 82 can be cleaned of soiling by friction cleaning or a wiping process can be carried out. The first active device 70 does not touch the surface 72 to be cleaned (when the cleaning nozzle device 10 in FIG an operating point working range of the surface to be cleaned 72 is located). It can also be made a fluid loading of the surface to be cleaned 72 or it can be turned off. When the second actuator 82 is in the second position 174 and the cleaning nozzle device 10 is maintained in an operating point range, the suction ports 46 are spaced a greater distance from the surface 72 to be cleaned as compared to the case when the second actuator 82 is in the working position first position 168 is. The distance can be so great that there is no more suction on the surface 72.

An operator can also guide the second active device into the third position 176 by actuating the actuating element 146. In this third position 176, the fluid nozzle device 76 lies between the first active device 70 and the second active device 82. It is then possible for both the first active device 70 and the second active device 82 to contact the surface 72 to be cleaned within the scope of the operating point range. It can then be done, for example, both a friction cleaning and a removal with simultaneous fluid loading and suction. An operator can then also by slight variation of the angular position, without leaving the operating point range, set whether only the first active device or only the second active device 82 to contact the surface to be cleaned 82. The cleaning nozzle device 10 is a multi-function device with which different cleaning operations (fluid charging, drawing, sucking, rubbing, wiping) can be performed simultaneously or sequentially without having to make a change to the cleaning nozzle device or to change the nozzle device. According to the invention a comfortable switching with respect to various steps (friction cleaning including wiping, vacuuming, wiping and suction simultaneously, etc.) in a compact design of

Cleaning nozzle device 10 is provided. A second exemplary embodiment of a cleaning nozzle device according to the invention, which is shown in FIG. 10 in a sectional view and designated therein by 180, wherein the same reference numerals are used for the same elements as in the cleaning nozzle device 10, comprises a

Actuator 182 which is rotatably formed on a housing 184 of the second portion 16 of the holder 12.

The housing 184 includes a base 186 and a top 188.

The actuating element 182 has a shaft 190, which is rotatably mounted, for example, in the lower part 186 via a corresponding rotary bearing. A gear 192 is non-rotatably mounted on the shaft 190. This gear 192 is rotatably positioned in a space 194 on the lower part 186. An axis of rotation 196 is oriented transversely and in particular perpendicular to a surface of the upper part 188.

The second active device 82 is positioned on a slide track device 198. This link path device 198 comprises a driver element 200. In the driver element 200, the second active device 82 is guided via a link element 204 via a link path 202. The link element 204 is, for example, a pin element which is fixed

(immovable) is arranged with respect to the second active device 82 and is immersed in the slide track 202.

With the driver element 202 is firmly connected to a rack 206. The toothed bar 206 has an extension direction transverse to the axis of rotation 196. The toothed wheel 206 acts on the toothed bar 206. The toothed bar 206 extends away from a remaining surface of the driver element 202

Direction of the lower part 186. The space 194 is formed between the driver element 202 and a bottom of the lower part 186 and the rack 206. By rotation of the actuating element 182, the gear 192 is rotated, which acts on the toothed bar 206. As a result, the driver element 200 is moved in a direction which is perpendicular to the axis of rotation 196. In the drawing according to FIG. 10, this direction of movement is perpendicular to the plane of the drawing. This movement in turn can be converted into a displacement movement of the second active device 82 in the displacement direction 98 via the slide track 202.

The second active device 82 has as excellent positions the first position 168, the second position 174 and at least one third position, which lies between the first position 168 and the second position 174. This at least one third position can be achieved for example by appropriate design of the slide track 202. It is also possible for a toothed gear mechanism comprising the toothed wheel 192 and the toothed bar 206 to be self-locking, so that there is a fixation at each rotational position of the actuating element 182. In this case, a plurality of lockable intermediate positions (corresponding to a plurality of third positions) may be provided between the first position and the second position.
